Medal Count 2016 Olympics: Twitter Reacts to Sunday's Standings and Results

Sunday saw multiple world records fall at the 2016 Summer Olympics in Rio de Janeiro, and the most decorated Olympian of all time took the pool for the first time this year. As a result, social media was abuzz throughout the day. 

Following Sunday's festivities, the United States owns a slim lead over China in the overall medal table. Italy, Japan and Australia round out the top five, per NBCOlympics.com:

Place	Country	Gold	Silver	Bronze	Total
1	United States	3	5	4	12
2	China	3	2	3	8
3	Italy	2	3	2	7
4	Japan	1	0	6	7
5	Australia	3	0	3	6

Golden State Warriors star Stephen Curry saluted the work Team USA did in the pool Sunday:

Four Americans won individual medals in swimming events, while the U.S. men's 4x100-meter freestyle relay team also placed first. Chase Kalisz won silver in the men's 400-meter individual medley Saturday, and he was swelling with pride watching his fellow swimmers carry the flag:

Katie Ledecky put together by far the most dominant individual performance. Perhaps motivated by her second-place finish in the women's 4x100-meter freestyle relay the night before, Ledecky set a world record in the women's 400-meter freestyle.

She finished in 3:56.46, nearly five seconds ahead of second-place finisher Jazmin Carlin. ESPN Stats & Information's Paul Carr added perspective to Ledecky's margin of victory:

The 19-year-old had The Cauldron's Julie DiCaro feeling inspired:

Phelps added a 23rd medal to his already unprecedented haul. He teamed with Caeleb Dressel, Ryan Held and Nathan Adrian to get his 2016 Olympics started out with a bang. Team USA finished the relay in 3:09.92, just ahead of France, who touched the final wall in 3:10.53. NBC Olympics shared a photo of the victors:

Houston Texans star J.J. Watt was amazed by the 31-year-old Phelps, who's competing in his fifth Olympics:

Americans weren't the only ones making history at the Olympic Aquatics Stadium. Sweden's Sarah Sjostrom set a new world-record mark in the women's 100-meter butterfly after winning in 55.48 seconds. On the men's side, Great Britain's Adam Peaty, who had already broken the world record in qualifying, one-upped himself in the 100-meter breaststroke final with a 57.13-second swim.

British sprinter Asha Philip shared a look inside Great Britain's watch party for Peaty's win:

In addition to plenty of dramatic finals, Sunday also provided entertaining play in the qualifying rounds.

Juan Martin del Potro upset the No. 1 player in the world, Novak Djokovic, in the first round of the men's singles tournament. It looked like the final round of the event based on the emotions of the two players. They shared an embrace on the court after the match, per NBC Sports:

NBC Olympics also provided Del Potro's post-match interview:

FiveThirtyEight's Carl Bialik thought Djokovic's humility in defeat made the moment even more special:

Sunday saw the beginning of the women's portion of the artistic gymnastics event. The United States, led by Simone Biles, is expected to win all-around team gold, and the team didn't disappoint. Team USA posted a cumulative score of 185.238, a little under 10 points better than China, which sits in second place.

Aly Raisman, who, along with Gabby Douglas, is competing in her second Olympics, tweeted out her reaction to her team's performance:

Simone Biles more than lived up to the hype as well. She leads in individual all-around and posted the highest scores in the vault, balance beam and floor exercise.

The women's team final is set for Tuesday, with the individual finals later on in the week. Biles and the rest of Team USA certainly set the bar high for the rest of the competition.
